Abstract

Fast-scan differential pulse voltammetry (FSDPV) is an electroanalytical technique that uses high scan rate to record voltammograms within several milliseconds and ensures high temporal resolution. Here, a FSDPV on a glassy carbon working electrode in combination with a flow injection analysis (FIA) system was developed and characterized using the hydroquinone/quinone redox system. Later, enhanced resolution of the technique was confirmed with the parallel determination of caffeic acid and p-coumaric acid. Finally, the optimized procedure has been applied for the first time to determine capsacinoids in chili pepper and total phenols in extra virgin olive oils. The proposed procedure is fast, simple, and enables the monitoring of complex samples in real-time.
